US 2016/0105324 A1 · Method and System for Information Interaction Among Systems in the Same End in DRNI

Abstract

Disclosed are a method and system for information interaction between systems in a same portal in a distributed resilient network interconnection, wherein the method is applied to each system in an portal in a link aggregation group, including: sending a distributed relay control protocol (DRCP) message through an intra-portal interface, wherein at least system information of a present system is carried; after receiving a DRCP message sent by an adjacent system, if it is determined that the present system and the adjacent system can form one portal in the distributed resilient network interconnection, determining an operational Key value of the present system. The system includes: a sending state machine, a receiving state machine, a negotiating state machine, a synchronizing state machine and a periodic sending state machine.

A method for information interaction between systems in a same portal in a distributed resilient network interconnection, used in each system in a portal of a link aggregation group, comprising:

sending a distributed relay control protocol (DRCP) message via an intra-portal interface, wherein at least system information of a present system is carried;
after receiving a DRCP message sent by an adjacent system, if it is judged that the present system and the adjacent system can form an portal of the distributed resilient network interconnection, determining an operational Key value of the present system.

A system for implementing distributed relay control in a distributed resilient network interconnection, comprising:

a sending state machine, configured to:
when other state machines in the present system instruct Need to transmit or Need to transmit periodically, send a distributed relay control protocol (DRCP) message;
a receiving state machine, configured to:
receive a DRCP message sent by an adjacent system, perform a matching check on system information of the present system and the adjacent system, record information in the DRCP message after the matching check is passed, and start a timer to judge whether the DRCP message sent by the adjacent system again is received on time;
a negotiating state machine, configured to:
determine an operational Key value of the present system, and ensure that the operational Key value is consistent with an operational Key value of the adjacent system;
a synchronizing state machine, configured to:
establish a forwarding channel between an aggregator/aggregation port and a gateway, negotiate a unified conversation distribution way with the adjacent system as required, and configure the conversation distribution way of a distributed relay;
a periodic sending state machine, configured to:
decide to periodically send the DRCP message by the sending state machine.
